In Chicago we don't have many mountains or even boulders to climb on so a friend and I have taken up “bridging”.  Basically we do long bouldering traversals on bridges.  Well, last night we learned that apparently one of the areas that is best for bridging has a problem with male prostitution.  Two officers of thee law stopped us as we were packing up our shoes and questioned us thinking we were male prostitutes....I think next time we go out we are going to have to wear shirts which read “Not For Sale”.  As soon as I can get my hands on a digitial camera I plan on posting locations and topos of our favorite bridges.
